Your report might also comment on inspection and maintenance requirements for your shop sawhorses. You certainly should have inspected the sawhorses which are out there, so you know what exists, and maybe what needs fixin. load per sawhorse, then your safety instructions. Don’t get too complicated with the allowable loads, this just get confusing for the shop center point load and uniform load on top HSS, and max. Of course, your report should show all of your assumptions, FoS’ and allowable cap’ys. the two legs, tying them together, and immediately under the top HSS to carry it? In effect, determine all these various member and joint cap’ys., then work back to all your imagined loadings.Įdit: If you are doing this for your own shop (or a client for that matter), and to satisfy your insurer, you might suggest to your boss that you could give a safety talk on sawhorse usage to your shop people. Check top HSS for bending and shear cap’y. Same reason the legs splay side to side, as relates to lateral loads and your sagging rebar bundle.Ħ. The feet of the legs should splay out beyond the end of the top HSS, so they can’t tip the horse over endwise. The two legs on one end can be overloaded too, actually lifting the other two legs off the floor. Yes, one web of the top HSS could carry much of the load and thus the legs on that side too. And, you have already listed a few of them, add lateral loads on the top HSS. All the worst possible loads in the worst possible ways, positions, orientations, etc. All of these are up to your engineering judgement and experience out in the shop.ģ, 4 & 5. Certainly, they will drop loads on them, so impact is worth considering. So, a high FoS is a reasonable assumption to start with, since the shop will find ways to use that up. You pretty much have to imagine all the ways the shop may misuse them and be sure that situation is not a killer or maimer. The shop assumes that if material will fit on them, they must be able to support it, come what may. They are used pretty indiscriminately, not well maintained or cared for, sit out in the rain to rust until needed again, sometimes cut while cutting the material they are supporting, etc. shop are not unlike many reusable components in a lifting system which are covered by the ASME BTH - 1 Std. And, as you get into your analysis, you will add to that list. Well…, you’ve got a pretty good start at the list of things you should check.
